Expandable Wireless Storage Device for Streaming a Mujlti-Media File

1. A method of streaming a multi-media file using an expandable wireless storage device, the method comprises: detecting that external memory has been physically coupled with an expandable wireless storage device that has internal memory; presenting an aggregated file system view to a user of the expandable storage device of the multi-media files that reside on the external memory and the internal memory, wherein the aggregated file system view presents to a user the mufti-media files that reside on the internal memory and the external memory as if the multi-media files resided on the same memory; and streaming a multi-media file to a playing device in response to a selection of the multi-media file from the multi-media files presented in the aggregated file system view.

2. The method as recited by claim 1 , wherein the multi-media file is stored on the external memory and wherein the method further comprises: providing a buffer that is at least a portion of the internal memory for streaming the multi-media file from the external memory to the playing device.

3. The method as recited by claim 1 , wherein detecting that the external memory has been physically coupled with the expandable wireless storage device that has the internal memory further comprises: detecting that the external memory has been physically coupled with the expandable wireless storage device that has the internal memory, wherein the internal memory has a faster transfer rate than the external memory.

4. The method as recited by claim 1 , wherein the method further comprises: determining whether performance of the external memory is sufficient to adequately stream a multi-media file to the playing device.

5. The method as recited by claim 4 , wherein the method further comprises: reading data from the external memory to the expandable wireless storage device; and calculating a transfer rate of the read data.

6. The method as recited by claim 4 , wherein the method further comprises: if the performance is not adequate, using an internal buffer of the expandable wireless storage device as a part of streaming the multi-media file to the playing device; and if the performance is adequate, streaming the multi-media file from the external memory to the playing device without using the internal buffer.

7. The method as recited by claim 1 , wherein the multi-media files are stored on more than one type of file system and wherein the method further comprises: presenting an aggregated file system view to a user of the expandable storage device of the multi-media files that reside on the more than one type of file system.

8. An expandable wireless storage device comprising: an interface slot for physically coupling the expandable wireless storage device with external memory that is for storing a first subset of multi-media files; internal memory for storing a second subset of the multi-media files; a wireless interface for streaming a mufti-media file In a playing device, wherein the multi-media file is selected from a group consisting of the first subset of multi-media files stored on the external memory and the second subset of the multi-media files stored on the internal memory and wherein the internal memory is used as a buffer when the multi-media file resides on the external memory; and an aggregated file system view providing component for providing an aggregated file system view of the first subset and the second subset of the multi-media files, wherein the aggregated file system view presents to a user the multi-media files that reside on the internal memory and the external memory as if the multi-media files resided on the same memory.

9. The expandable wireless storage device of claim 8 , wherein the external memory belongs to a type of memory selected from a group consisting of secure digital (SD) card, micro-SD card, universal serial bus (USB) flash drives, compact flash and secure digital high capacity (SDHC).

10. The expandable wireless storage device of claim 8 , wherein the internal memory is flash memory.

11. The expandable wireless storage device of claim 8 , wherein the expandable wireless storage device is a mobile device.

12. The expandable wireless storage device of claim 8 , wherein the aggregated file system view is provided, at least in part, by logical blocks that span the internal memory and the external memory.

13. The expandable wireless storage device of claim 8 , further comprising firmware that supports logically storing the multi-media files on each of the internal memory and the external memory and maintaining a high level representation of the multi-media files that can be used to present the internal memory and the external memory as a single aggregated storage volume to a user of the expandable wireless storage device.
